To all whom t may concern.'

Be it known that I, ARTHUR J. WIDMER, a citizen ofthe United States, and a resident of Webster Groves, in the county of S't. Missouri, have invented Supports,

intenti "'n insbes panieunriy i0' eil- It in y fon'ribbedeonerete vorfhollow tile concrete floors, lw

hereinv the spaces between the ribsorbe'neath theftiles are spanned byceillng beards, the' .under sides of which are i plastered to niake a smooth ceiling.

The .object of theinvention is to provide a simple, 'secure-and'inexpensive means for supporting the plaster boards from the concrete of the floor;v 'A further object of the invention is to saveA time and labor, in placing the supporting means and in attach- -inv the ceiling boards thereto.

he invention consists in a tie or anchor which is driven from above into the formwork for the floor concrete prior to concreting the Boor, and which remains securely embedded in the concrete when the forms below the are removed with its lower end projecting boards to:

Furthes .details of the invention appear below in connection with the description of the several forms thereof illustrated in the accompanying drawings/and what thel` invention consists in is more particularlyi'deined in the appended claims. l

In the drawings, wherein the same reerence characters designate the saine parts in the several views, j

Figure 1 is a cross-section of a ribbed concrete floor/through va rib, showing the iioor after the concrete has been poured and prior to the removal of the forms;

drawn to a largerjscale, showing a modified form of' anchor and ceiling board tie; f

Fig. 9 is a perspective view -of another anchor .similar to those shown' in Figs. 2 and 3;

Fig. l0 is a those shown in Figs. 2 and 5; and

vFig. 11 is a plan view of a tie plate like those shown in Figs. 3 and 4. j j

ln the construction shown in Figs. 'l and 2, the floor forms 10 are laid on the formwork l1, and anchor ties 12V are driven into the formwork between the forms, after which the concrete 413 is poured, as shown in Fig. 1. The anchor tie's have flexible portions 14 the formwork up to the shoulders l5. Upon removing the formwork, the iiexible end portions. 14' are left projecting belowthe surface of the concrete. j

The ceiling boards 16 are secured in place fagainst the under side of theconcrete by `"fnief'ins of metal plates 17I which lap under their edges, and which are held: up by the anchor ties 12. The depending ends 14 of the anchors project down throughholes 18 in the plates '17, and are the plates in place, as shown in Figa.

'In Fig. 3 another means of secnring the ceiling boards 16 is shown. The edges of the ceiling boards rest upon plates 19, which are supported by wires 20 from the project# ing ends of the anchors lei.l The lower ends of the anchors le are bentlip to form hooks 21 over which the wireswae looped, the

. lower ends ofthe wires bein slots 22 in the edges of thev plates 19 and tied togetherbelow the plates.

In the form of theinvention illustrated in Fig. 4,' the anchors 23 are sheet metal strips having slotted holes24 at their lower ends orthe wires 20 which hold up the which support Athe plaster boards other modifications of the anchor' bent over to hold `passed throughL Fig. 8 is a perspective view, partly in secplan view.. of a tie plate like at their ends which are driven into I BEST AVAILABLE cos square shoulder 25, as shown in Fig. G. This shoulder brings up against the form work ,to position the anchor at the proper depth in the concrete.

The anchor 26 shown in Figs. 5 and 7 is i sheet metal like that shown in Figs. l and 6, but has two holes 2T one-above the other near its point. A nail 28 arranged crosswise through ,the upper hole in the anchor strip 26 forms a-shoulder to engage the form work and position the anchor at the proper depthrin the concrete. The plate 17 which supports theplasterboar'ds is held up by a second nail 29 arranged crosswise through the lowerhole 27 in the anchor 26.

- Figs. 8 and 9 illustrate still further modiications of the invention. Fig. 8 showsan anchor consisting ofa wire nail 30 with a sleeve 31 on it to stiden it above the point.

The sleeve is shorter than the nail and I forms a spacer for positioning the anchor above the forms to project down below the concrete thedesired amount after the forms are removed. Fig. 9 shows an anchor consisting of a wire nail 32`having an enlargement 38 near its point end to form a shoulder for positioning the anchor abovev the forms V1n the concrete.

It is evident from the foregoing descrip- -v tion that various forms of anchors, ties and plates may be used without departing from the invention; and the invention. is not re strictcd to the forms shown and described. A I claim the following as my invention: 1. The method of constructing a ceiling for a concrete Hoor which comprises driving 4o an anchor having a pointed lower end into the formwork, embedding the upper end of said anchor in the floor concrete, removing the centering to expose the pointed end of said anchor, and attaching ceiling supporting means to said exposed end.

' 2. The method of constructing a plastered ceiling for a ribbed concrete Hoor which comprises driving an anchor having a pointed lower end into the formworlr for a rib,

embedding the upper end of said anchor in the Hoor concrete, removing the centering to expose the pointed end of. said anchor, attaching ceiling supporting means to said exposed end, and arranging plaster supports for said ceiling against the under side of the rib on each side of said ceiling supporting means and supporting said plaster supports on said means. A

3.The method of constructing a ceiling for aconcrete Hoor'which comprises drlving an anchor havinga pointed lower end and a shoulder adjacent to said pointed end into the formwork as far as said shoulder, embedding the upper end of said anchor in the floor concrete, removing the centering to ex- 65 pose the pointed end of said anchor, and attaching ceiling supporting means to said exposed end. i 4. In combination with a concrete floor, a ceiling vcomprising plaster boards spaced apart at their edges, and means for supporting said plaster board ceiling, said means consisting of spaced anchors partly ernvbedded in said door, said anchors having integral portions adapted to be driven into the door forms and projecting 'below said floor between said plaster boards and having hooks at their lower ends, and metal lates arranged beneath 'the edges of ythe p aster boards and held up by said hooks. 80

5. In -combination with a concrete floor and ceiling construction, spaced anchors partly embedded in the under side of said floor, the exposed fportionof-said anchors having integral `portions adapted to' be 85 driven into theioor forms and projecting below said floor and having hooks at their lower ends, wires Iengaging the lower ends of said anchors, and plates sustained byfsaid wires` for supporting plaster boardsand a 9 0 plaster` ceiling 4.ct/)vering said wires and plates. l

6. In constructing a concrete floor and ceiling,vdriving anchors into the formsn rows and subsequently embedding them in concrete, removing the forms to expose the driven ends of said anchors, arranging ceiling boards with gaps between their edges, said gaps being beneath and in alinement with said rowsof anchors, the exposed ends of said anchors projecting through said gaps, arranging rows of supporting members for said ceiling boards across said gaps beneath said boards, and fastening said supporting members to the exposed ends of said anchors.

7. A ceiling construction` for a concrete Hoor, said ceiling comprising plaster boards spaced apart inl rows, metal plates lapping under the edges of boards of adjacent rows for supporting themV at intervals, anchors embedded inthe concrete with their lower ends projecting between the plaster boards,

'and flexible retaining members for sustaining said-plates from said anchors, said plaster boards, plates and retaining members being covered by plaster to produce a smooth 8. ceiling for f i'loor havin concrete ribs, said ceillng comprising plas er boards ,1' arranged in rows beneath said floor, the edges of the rows being in Ialinement with said ribs, anchors partly embedded in said ribs and proecting between the edges of said plaster cards, and plates supported by said anchors and projecting under the eldges of said plaster boards for supporting t em.
